Title: Improvements in or relating to Steel Studs for Studding Boiler Tubes.
Inventor: OEHLER WERNER
IPC: F16L55/00
Filed: 1966-12-22
Abstract: 1,174,416. Jointing by rolling; lathe details; welding by pressure; making studs. L. & C. STEINMULLER G.m.b.H. 22 Dec., 1966, No. 57457/66. Headings B3A, B3M, B3R and B3T. [Also in Divisions C7 and F2] Stud for boiler tubes is made by shrinking a high alloy steel sleeve (i.e. containing more than 20% of additives) on to an unalloyed or low alloy steel billet (i.e. containing less than 20% of additives), rolling and/or drawing the body thus formed down to a bar having the cross-section of the finished stud, and dividing the bar into studs. The dividing tool (Fig. 5a, not shown) produces a stud in which one end face of the core is conical or convex. The other end face may be sprayed and coated with high alloy steel. The conical or convex end of the core is welded into a corresponding recess in a boiler tube. The alloys have compositions described in Division C7.

Title: Method of making a patterned metal film
IPC: H05K3/18
Filed: 1970-12-04
Abstract: 1326046 Selectively plating a metal on an insulating substrate RCA CORPORATION 4 Dec 1970 [10 Dec 1969] 57840/70 Heading C7F [Also in Division H1] A method of selectively plating a metal on an insulating substrate comprises depositing an organic resist material in a predetermined pattern on the substrate so as to leave portions of the substrate exposed, sensitizing and activating both the exposed portions of the substrate and the surface of the resist, treating the sensitized and activated surfaces with an etching solution so that only the exposed portions of the substrate are deactivated, and treating both the activated and deactivated surfaces with an electroless metal plating bath so that the metal deposits only on the activated surface of the resist material. The substrate is preferably glass and the resist material is preferably a photo-resist such as dichromate sensitized polyvinyl alcohol or dichromate sensitized fish glue. After drying, the photo-resist layer is exposed to a pattern of light and shadow and then developed with water. The resist pattern and substrate are then sensitized and activated using SnCl 2  and PdCl 2  respectively, and optionally heated at 200C. for 15 seconds. The entire surface is then treated with an etchant such as nitric, sulphuric or hydrochloric acid which dissolves the palladium from the surface of the glass but not from the pores of the resist surface. The unit is then immersed in a solution from which the desired metal e.g. Ni, Co, Cu, Mo, W or Fe can be deposited. To deposit Ni together with a small amount of boron, a solution comprising NiCl 2 , Na 4 P 2 O 7 , NH 4 OH and (CH 3 ) 2  NHBH 3  may be used. CoSO 4  may replace the NiCl 2  if Co is to be deposited and NaH 2  PO 2  may replace the (CH 3 ) 2  NHBH 3  if some phosphorus is also to be deposited. After deposition is complete a layer of copper may be deposited electrolytically, the product covered with a resin which is then allowed to set, and the unit stripped away from the substrate to form a flush-type printed circuit. Activators other than Pd include Fe, Co, Ni, Ru, Rh, Os, Ir, Pt, Cr, Ag, Au and Cu.

Title: Hydrodynamic transmission for cranes or the like
IPC: F16H45/00
Filed: 1969-12-11
Abstract: 1,246,196. Hydro-dynamic transmission control; friction clutches. TWIN DISC Inc. 11 Dec., 1969 [26 Dec., 1968], No. 60462/69. Headings F2C and F2L. A power transmission for a crane wherein an engine E drives the impeller I of a stationary housing type torque converter TC through an hydraulically actuated continuously slipping multi-disc clutch MC, a single control valve CV controls the engagement of the clutch MC and the filling of the torque converter TC and a bleed passage 20 vents the torque converter when its turbine T rotates reversely during load lowering. The control valve CV regulates the loading pressure supplied from a pump P to a relief valve RV and a clutch discharge valve OV. The valve RV regulates the pressure supplied by a pump 17 to the torque converter working circuit within the range from zero to 45 p.s.i. whilst a valve BPV limits the pressure supplied to the torque converter working circuit. The loading pressure supplied to the valve OV acts, in opposition to centrifugal force and the action of a spring OVS, on the outer end of a valve spool 23 to move the latter inward and close an exhaust passage (26) from the clutch servo chamber (25) which is continuously supplied with pressure liquid from the pump 36 through a restriction (28C). A centrifugal governor G driven by the torque converter output shaft 13 modulates the loading pressure supplied by the control valve CV to the clutch control valve OV to limit the maximum output speed of the torque converter. The maximum output speed of the torque converter may be adjusted by a lever 33 which loads the governor G. Liquid bled from the torque converter through the bleed passage 20 passes through the clutch to cool the latter.

The lengths may extend transversely of as in Fig. 1 or circumferentially around the tyre (Fig. 2, not shown) to form a chain network with the adjacent links 13 which lie perpendicular to the tread interconnected by the connecting elements 14 and the parallel links 12, each having a cross-bar 15 in the form of an oval round-steel link which reduces the wear on the chain and the load on the perpendicular links. For fastening together the ends of the chain around the tyre locks 16 are used in place of connecting elements 14. On the longitudinal sides of the chain network, Fig. 1, connecting elements 14 connect perpendicular links 13 with perpendicular links 17 of side chains 18, while with circumferentially extending chain lengths (Fig. 2, not shown), one or multiple piece connecting elements (27, 28, 29) having profiled sections like the elements 14 connect alternative perpendicular links of side chains (30, 31).

Title: Coin Freed Vending Machine
IPC: G07F5/08
Filed: 1979-03-22
Abstract: In a coin freed vending machine of the kind incorporating a coin released vending member such as a drawer 4, the release of the member 4 is determined by the vertical position at which a slide 6 is arrested during downward movement of the slide 6 which accompanies an attempt at movement of the member 4. The slide 6 is arranged adjacent a coin insertion chute 5 within which are stacked coins inserted into the chute 5 and resting upon an abutment surface 17. The slide 6 carries one or more pawls 10 projecting into the chute 5, and arranged to be arrested by a stack of coins during downward movement of the slide 6. Release of the mechanism is therefore dependent upon the vertical height of a stack of coins above the abutment surface 17. The provision of more than one pawl 10 may allow for release of the machine by means of different combinations of coins which form stacks of different height but have the same monetary value. <IMAGE>

Filed: 1979-03-28
Abstract: A single-pole electrical switch comprises a longitudinally-movable contact 1, a longitudinally-movable guide stem 2 biassed by a spring 9 towards the contact 1, and a contact lever 6 pivoted at one end to a fixed bracket 10 and pivotally connected by a pin-and-slot connection 13, 6a to the guide stem 2. The lever 6 extends obliquely across the path of movement of the contact 1 and presents to it a concave cam surface 6b, along which the contact 1 slides after its initially engagement with the lever 6 on closure of the switch, so that continued travel of the contact 1 will pivot the lever 6 about the bracket 10 and will depress the guide stem 2 against its spring 9. The switch may be used to switch a resistor 4 into a circuit in timed relationship with the closure of a main circuitbreaker or isolator in the circuit. Adjustment of the starting position of the guide stem 2 by means of a nut 7 enables the contact gap and contactengagement timing of the switch to be adjusted. <IMAGE>
